Why does water go down the plughole a different way once you cross the equator?
If you're looking to find out if the theory is true that it spins differently in the 2 hemispheres, it is true. In Uganda, right on the equator there was a demonstration of this gravity effect. They had a large funnel on each side of the line, about 20 ft away, and one right on the line. They poured water in, set a leaf on the water for visual aid, and stilled the water. When they released the hole in the bottom, the water spun opposite directions on the 2 sides. When they did the same test on the line itself, the water didn't spin at all. It dropped straight thru the hole. When the dish became just a tiny bit off center, the water began to spin. Only directly in the center of the equator did it not spin. Amazing!

Although the principles of coriolis forces are well established, the forces involved in water going down the drain are so small that coriolis has less effect the the beating h…eart of the observer. So forget it--it's urban legend.. Er, the link below is to a demonstration on YouTube of the coriolis effect at the equator, showing that water does indeed go straight down. . http://www.youtube.com/watch?v=ZU1EB0z-h7w
it goes left i think jk lovrz yall hehehehe jkjkjkj
Downward. That is, toward the center of the Earth.
Contrary to popular belief, the water is not affected by the motion of the Earth, or by which hemisphere the bowl is in. Water drains in a downward direction. How water goe…s down the plughole is determined by the state of the water when the plug is pulled, the construction of the bowl, and the shape and size of the plughole. It doesn't always go the same way. The vortex direction is dependent on small local factors, and the slightest impulse (motion, temperature) makes it unpredictably random. On a larger scale, the airflow into cyclones in the Northern Hemisphere is counter-clockwise, and in the Southern hemisphere clockwise. So if the Coriolis effect were the dominant factor, that would be the direction of the draining.
quite possibly in the direction of the sea.
The vortex would depend on the side of the planet your on as gravity determines the direction
It may go down in any direction - depending on how the water was spinning at first. If the faucet which you use to fill a container is ever so slightly inclined to the left or… to the right, this will give the water a spin that will last for at least a day. Coriolis effects - effects due to the rotation of the Earth - are usually quite secondary.
On the average, it goes directly toward the center of the earth, although it may proceed via a circuitous route, including circular rotation in either direction.
Answer: anti-clockwise Answer: It may go down the drain in any direction, depending on previous conditions, and the shape of the drain. Coriolis effects are too small Tobe… noticeable at such a small scale.
Water drains clockwise or counter-clockwise depending on many factors, such as the shape of the drain and basin, the velocity vector of the injection water, etc. Unless the dr…ain is very, very large, on the order of many miles, the effect of the difference in planetary rotational speed north or south of the equator (the so called Coriolis effect) is inconsequential. However, as can be seen from the rotation of hurricanes, the Coriolis effect tends to "turn" moving objects to the right. But the flow into a Northern Hemisphere hurricane moves in a counter-clockwise direction (moving from higher pressure to lower pressure). This would be the case for water draining with no other influence. In the Southern Hemisphere, this would be reversed to clockwise (as are cyclonic flows). But generally, smaller local factors make directional draining unpredictably random.
it wold inter change or go strait down
Contrary to popular belief, it has nothing to do with the latitude or the Coriolis effect. Toilets and sinks drain in the directions they do because of the way water is direc…ted into them or pulled from them. The Coriolis effect is the reason why hurricanes rotate clockwise in the southern hemisphere, and counterclockwise in the northern hemisphere. But you need a very large amount of moving air and water for it to take effect.
